Hi,
Travis Hassloch suggested I ping Linux folk here locally (SFBay Area -- I'm in
Redwood City) and so here I am, and here's the problem:
I have a linux (well, ubuntu 10.04 and greater apparently (I'm running the
former)) scancode/keycode problem on a Dell E6500 (as well as similar Dell
systems apparently) and am not sure how to fix it.
The terse problem description is: "Dell E6500 fn+f8 switch video mode (external
monitor) does not work".
Unfortunately, I'm a linux/ubuntu internals n00b. AFAIK/AFAICT, it ought to be
a tweak to scancode->keycode map(s) and/or X modmap, but from the manpages I'm
not sure how to accomplish it with the limited time I have to try to fix it.
I /think/ I've figured it out to a fair degree, and have described the problem
in detail in various places (sometimes appending a comment to someone else's
original post) listed below, but as yet have not secured any help.
This diagram of Travis' is helpful in understanding this stuff:

..and in looking at it, it'd appear that my particular issue may well be with
the X "modifier map", managed by xmodmap(1). But the xmodmap man page is rather
obtuse and I'm not sure what sort of magic incantation might fix the fn+f8 problem.
Anyone know, or have further ideas?
thanks,
